Astro Products Reveal Focus Filter
The Astro Products Reveal Focus Filter is the quickest and most accurate way to focus on the Milky Way with DSLR lenses.
The Reveal Focus Filter will create six spikes on bright starts, or more accurately three lines that pass through bright stars. There is a main large line then a smaller cross-section of two lines making an “X”. The goal is to get the large line centered between the X and centered on the star. As soon as that is done BOOM you have perfect focus in as little as 2-3 seconds.
The 150mm Reveal Filter is good up to about a 135mm telescope or DSLR lens filter size.The 100mm is best suited for lenses that are about 90mm.If your filter on the front of the lens is under 60mm the 85mm size may work better and be snugger.
